What happens to the cable if it overloads? (It is just interesting) :)

itl2044: First it will start to swell, then through small microcracks will begin to dissipate ions, if you do not cut the shell in time, there can be an explosion, it is especially dangerous if the wire is thrown by the pioneers on the facade of the building, past the gas highways, so the attentive chiefs of the JECs in any case do not give the pioneers the keys from the roofs, that they do not pull dangerous networks.
But you can't cut the cable in advance, otherwise the air can get there, and the ions will fall out just so, from this very strongly begins to lie the network, some subscribers practice to cut the cable, and place the loop with the cut in a half-filled three-litre bowl with water.
In any case, do not disconnect the power supply until all traffic comes out of the twisted pair, otherwise the remains of traffic will dry, and cox, later on such a cable, the bandwidth will fall very strongly, and large packs will stop walking.
